WILLIAM F. YOUNGBLODT, OF DENVER, COLORADO.

BELT-FASTENER.

T all whom it may concern Be it known that I, VILLIAM F. YoUrjenLoDr, a citizen of the United States, reslding at the city and county of Denver and State of Colorado, have invented certain new and useful Improvements in Belt-Fasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to devices for fastening together the ends of belts, and more particularly to devices to be used with ply belts and interwoven belts.

The object of the invention is to provide a device, no portion of which Wlll lie on the surfaces of a belt.

Briefly, the invention comprises a member having oppositely extending prongs, the body portion of the member being adapted to be inserted in the body of the belt ends between the layers thereof, with the prongs extending outwardly toward the opposite faces. When in operative position the prongs will be clenched adjacent the belt surfaces. When these rivet members are used alone, half of the plies of each belt end will be cut away for a short distance, the remaining plies of the belt ends being overlapped, the prongs on one end of each device projecting through one belt end, and those on the other end of the device through the other belt end. The devices may also be provided on a plate, in which case the ends of the belts will abut and the plate will span the joint and lie between the plies of the belt ends. If leather belts are used, the belt ends will be split to receive the plates.

The rivet shown in Figs. 1, 2 and 3 comprises a body portion 20, from the opposite ends of which pairs of prongs 22 extend. These are used by cutting away one-half of each of the ends 24: of the belt or belts to be joined, or one-half of the plies thereof, when ply belts are used. The remaining halves of these belt ends are the overlapped and the ends caused to abut as shown at 26. The body portions of the rivets are positioned at the line of contact 27 of the opposing faces. If necessary, the plies may be perforated to allow for displacement by the body of each rivet. The outer ends of the prongs 22-are then clenched as shown, so that they will lie flush with the surfaces of the belt ends.

A plate or sheet 30 of metal, leather or rawhide may be used with the rivet 20, in which case the plate 30 will be perforated at 32 to receive the rivets 20. When using this form, the belt ends 3 1 will be caused to abut at 36, the ends of the belts being split and preferably the middle portion of each end, or the middle ply when a ply belt is used, being removed to provide space to receive the plate 30. As above described, the belt ends may be perforated to accommodate rivets.

In the form of Figs. 8 to 12, the rivets are integral with the plate 40, from which the prongs 42 extend. This form is used in precisely the same manner as that of Figs. 6 and 7. in the belt ends 44 to form a joint 46.

Here the plate 4.0 is positioned with- In the form of Figs. 13 to 18, single prongs 52, integral with the plate 50, are used instead of double prongs, as in the other forms. Here the plate 50 is inserted in the belt ends 54 to form a joint 56, the ends of the'prongs 52 being clenched flush with the belt faces.

When the plates 30, 40 and 50'are to be used to pass over relatively small pulleys, they will be slightly curved, as shown, in order to accommodate the pulley curvature.

It is obvious from the foregoing that the present invention provides a simple means for adjoining belt ends without causing any of the fastener to lie upon the belt surfaces. This condition exists by reason of the fact that the body of each fastener is contained Within the belt ends and the prongs are clenched to lie flush with the belt surfaces or, if necessary, below the surfaces.

I claim:

1. In combination, a belt fastener comprising a body member having a plurality of prongs at each of two opposite sides and extending from said opposite sides, belt portions lying on said opposite sides of said body member, said prongs extending outwardly through said portions toward the respective outer faces, the diameter of the body member being substantially uniform and approximately equal to the distance between outer faces of the prongs of eachpair.

2. A belt fastener comprising a substantially cylindrical body member inwardly split at its opposite ends to provide a pair of prongs at each end and a metal body portion of relatively shortlength.

Intestimony whereof I affix my signature.
